Spawning salmon

Spawning salmon are salmon that spawn, or getting ready to spawn

When the salmon comes swimming in from the ocean and up into the river, it is silver-shiny. After it has been in the river for a while, its appearance gradually begins to change. The silver sheen eventually disappears, the skin darkens, and we can sense an incipient hook on the lower jaw of the male salmon. The male salmon develop sperm, and the female salmon roe. That means the salmon are getting ready to spawn.

The male salmon decorate themselves the most

In late autumn, before the ice settles, the salmon spawn in many pupils. Then the spawning axis has decked itself out properly. The spawning suit of the male salmon is especially colorful and great. The male derives color and energy from the fish meat. The skin becomes reddish, and the lower jaw acquires a real hook. The hook is well suited for fighting with, and both the color and the hook should impress the female salmon.

The female does not become as colorful in the skin as the male salmon. She becomes more brownish. But the turnip grains acquire a bright orange color.

The skin of the spawning shaft becomes thicker, and the fish shells sit firmer. It is advisable to be hard-skinned when fighting and maybe stay in the river for a whole winter.

The spawning salmon spends plenty of time getting ready. Having remained relatively calm in the same place, perhaps for several weeks, it begins to look for the perfect spawning ground. It's a battle for the best seats. The strongest male is the boss.

The female salmon is in charge of the digging work

Rogna is laid in a spawning pit, which the female salmon digs. She uses her tail to dig and her gatear fin to measure the proper depth. The toughest male salmon is immediately in place and fertilizes the rowan when the female releases the eggs. The female salmon quickly covers the rogna with a layer of gravel.

Snipers

In the spawning grounds there are always some small tricksters that we call spawn pairs or snipers. These small paws are sexually mature salmon males that have not been on a nutrient migration in the ocean. They deceive themselves and help fertilize the rowan. They live dangerously and can be killed if they get in their way and are spotted.

Sneak spawners

Some male parrs become sexually mature and participate during spawning. We call them spawning parrs or sneak spawners. Those of them that survive the spawning may later travel to the ocean and return as spawning salmon. In the photo on the left you see a parr. If it is a male fish, it will either smoltify and travel to the sea or stay in the river and try itself as a sneak spawner. It can also be a trick strategy. Spawning pairs do not get as nice spawning attire as the large spawning salmons.
